"Electric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between maths- and theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little ...
k k DC Machines 347 For any of the following reasons a generator may fail to build up: 1. Too high a resistance to field-circuiting; including open circuit, which will reduce the field current to a very small value. 2. Low speed. 3.
Stator : It is the stationary part of the dc generator , which provides mechanical support for the machine and contains the field poles . Another part of a stator is yoke , which provides high permeable path for the magnetic flux .
